group by in files :-)

hellsd · #1 (**permalink**) 06-21-2005

My file looks like:

X^~^12^d
X^~^19^d
Y^~^5^d
Y^~^10^d
Y^~^11^d
Z^~^14^d

I need a script that will "group by" the first field and Concatenate the values.

My output should be:

X^~^12,19^d
Y^~^5,10,11^d
Z^~^14~d

Does anyone have any idea ?

Your post is on similiar lines to that of

shell script comparing files in a file

Check it out.

where the delimiter is ^ and if the concatenated field is not last.

Any idea ?

something to start with:

nawk -f hell.awk file.txt

hell.awk:

Code:

BEGIN { FS=OFS="^" }
{
    arr[$1] = ($1 in arr) ? arr[$1] "," $3 : $3
}
END {
  for (i in arr)
    print i OFS "~", arr[i]
}
